Abstract

Procedimiento de inyección de preformas, de soplado de las mismas y preformas y recipientes así obtenidos. Substituye la refrigeración por agua de la preforma para su inmediato soplado, por una refrigeración de desmoldeo que reduce el tiempo de fabricación de ésta, mediante la utilización de refrigerantes (3) líquidos diferentes, de baja o muy baja temperatura de ebullición, previo a la extracción de la preforma y, adicionalmente, evita la refrigeración para soplado de la preforma, así como que sirve para incrementar la vida útil del molde, al evitar su sudado, dada la ausencia del agua de refrigeración, que perjudica al acero, incorporando el asa un rehundido de extremo esférico, antitorsión y de rebosadero. Figura 1.Procedure of injection of preforms, blowing of the same and preforms and containers thus obtained. It replaces the water cooling of the preform for its immediate blowing, by a demoulding cooling that reduces its manufacturing time, by using different liquid refrigerants (3), with low or very low boiling temperature, prior to extraction of the preform and, additionally, it avoids the cooling for blowing the preform, as well as serving to increase the useful life of the mold, by avoiding its sweating, given the absence of cooling water, which damages the steel, incorporating the handle a recessed ball end, anti-twist and overflow. Figure 1.
